For this case we have the following equation:

Where, we have the following variables:
x: time in seconds
y: speed in feet per seconds
For the initial velocity, we evaluate x = 0 in the given equation:

Therefore, the initial speed is 12 feet per second.
Answer:
The particle's initially velocity is 12.
7 x 13 = 91.......so 91 is not a prime, it is a composite
Answer:
5
Step-by-step explanation:
2=30 so 30= 1/2 or an hour so 2+2=4 witch makes an gour half of 2 is 1 so it would make 5
Answer:
The answer would be B.
Because if you multiply all the numbers of ABC then go through the list of the A'B'C' options only B matches up
